Mammals in MZNA-VERT: project Loza

Description

This collection includes information of small mammals’ community found in Loza lagoon shores (Navarra, Spain). The study was carried out in Loza in 2007 and contains information of eight mammal species. The database is formed by 208 occurrences and 18 preserved specimens which are stored in MZNA facilities.

This collection is only a part of a large project carried out in Loza in which the purpose was to study the flora and fauna of this lagoon.

The data set is available in GBIF.

Geographic Description

The project was conducted in Loza Lagoon and all occurrences and specimens come from the surrounding area near the lagoon.

Purpose

The aim of the present data set is to provide all information of the records of small mammals from the project conducted in Loza Lagoon.

Data quality

All specimens collected in the field are deposited in the Museum of Zoology of the University of Navarra (MZNA, Pamplona, Spain) in the ‘Project Loza’ collection.

All the species were sexed and identified in field by Carmen Escala and David Galicia. Specimens from pellets were identified using suitable literature (Gosálbez 1987). Scientific names were validated according to Mammal Species of the World (Wilson and Reeder 2005, Palomo et al. 2007).

Coordinates in UTM/MGRS were transformed to geographic system. The consistency of all records was checked by visual inspection overlapping coordinates with a Navarra map using GIS (Chapman 2005) and their uncertainty was calculated in metres using the point-radius method.

Methods

Barn owl pellets were frozen at -20ºC for removing bugs. After that, pellets were dissected and skulls, mandibles and other bones were separated for taxonomic identification. Specimens were identified using a stereoscopic microscope and appropriate literature (Gosálbez 1987). Finally, specimens were placed in plastic bags with their unique catalogue number and stored in the museum facilities.

Specimens found dead were transported to laboratory where the skull was prepared. First, specimens were dissected separating skull and axial skeleton from the rest of the body. Then, they were boiled and flesh was removed from the bones. Once dried, they were placed in zip plastic bags with their unique catalogue number. From some specimens following measures were obtained: body length, tail length, ear length and hind foot length.
